There is in truth a strange reciprocity between instinct and self-consciousness, according to which they both play into each other's hands. This is above all true of great artists' work, which in a superficial sense might be called unconscious, but which in a deeper sense is profoundly conscious. It seems as though, in great works of art, a certain superficial reasoning is sacrificed to instinct, but in that very sacrifice a deeper level of reason is reached between which and instinct there is no longer anything but complete understanding.
To intellectualize instinct is one of the profoundest secrets of the art of life; and it is only when instinct is thus intellectualized, or brought into focus with the other aspects of the soul, that it is able to play its proper rhythmic part in the musical synthesis of the complex vision. But although we cannot allow to instinct the all-absorbing part in the world-play which Bergson claims for it, it remains that we have to regard it as one of the most mysterious and incalculable of the energies of the soul. It is instinct which brings all living entities into relation with something sub-conscious in their own nature.
Under the pressure of instinct man recognizes the animal in himself, the plant in himself, and even a strange affinity with the inorganic and the inanimate. It is instinct in us which attracts us so strangely to the earth under our feet. It is instinct which attracts certain individual souls to certain particular natural elements, such as air, fire, sand, mould, rain, wind, water, and the like; a kind of remote atavistic reciprocity in us stretching out towards that particular element. It is by means of instinct that we are able to sink into that mysterious sub-conscious world which underlies the conscious levels of every soul-monad. Under the groping and fumbling guidance of this strange power we seem to come into touch with the profoundest reservoirs of our personal identity.
Considering what fantastic and cruel tricks the lonely thinking power, the abstract reason, has been allowed to play us it is no wonder that this French philosopher has been tempted to turn away from reason and find in instinct the ultimate solution. Instinct, as we give ourselves up to it, seems to carry us into the very nerves and tissues and veins and pulses of life. Its verdicts seem to reach us with an absolute and unquestionable authority. They seem to bear upon them an "imprimatur" more powerful than any moral sanction. Potent and terrible, direct and final, instinct seems to rise up out of the depths and break every law.
It leaps forth from our inmost being like a second self more powerful than we are. It invades religion. It incarnates itself in lust. It obsesses taste. It masquerades as intuition. It triumphs over reason. With an irrationality, that seems at the same time terrible and beautiful, instinct moves straight to its goal. It follows its purpose with demonic tenacity, heedless of logic, contemptuous of consequences. It cares nothing for contradictions. It forces contradictions to lose themselves in one another according to some secret law of its own, unknown to the law of reason.
Such, then, is instinct, the sub-conscious fatality of Nature so difficult to control; whose unrestrained activity is capable of completely destroying the rhythm of the complex vision. Nothing but the power of the apex-thought of man's whole concentrated being is able to dominate this thing. It may be detected lurking in the droop of the Sphinx's eyelids and in the cruel smile upon her mouth. But the answer given to the challenge of this subterranean force is not, after all, any logical judgment of the pure reason. It is the answer of the vision of the artist, holding its treacherous material under his creative hand.
Let us turn now to the attribute of "intuition." Intuition is a thing more clearly definable and more easily analysed than almost any other of the aspects of the soul. Intuition is the feminine counterpart of imagination; and, as compared with instinct, it is a power which acts in clearly denned, isolated, intermittent movements, each one of which has a definite beginning and a definite end. As compared with imagination, intuition is passive and receptive; as compared with instinct it does not fumble and grope forward, steadily and tenaciously, among the roots of things; but it suspends itself, mirror-like, upon the surface of the unfathomable waters, and suspended there reflects in swift sudden glimpses the mysterious movements of the great deep. In this process of reflecting, or apprehending in sudden, intermittent glimpses, the mysterious depths of the life of the soul, intuition is less affected by the reason or by the will than any other aspect of the complex vision.
Instinct, in secret sub-conscious alliance with the will, is a permanent automatic energy, working in the hidden darkness of the roots of things like an ever-flowing subterranean stream. The revelations of intuition, on the other hand, are not flowing and constant, but separate, isolated, distinct and detached. In the subject-matter of their revelations, too, intuition and instinct are very different. If the recesses of the soul be compared to a fortified castle, instinct is the active messenger of the place, continually issuing forth on secret errands concerning the real nature of which he is himself often quite ignorant. Intuition, on the contrary, is the little postern gate at the back of the building, set open at rare moments to the wide fields and magical forests which extend to the far-off horizon.
Instinct is always found in close contact with sensation, groping its ways through the midst of the mass of material impressions, acting and reacting as it fumbles among such impressions. Intuition seems to deal directly and absolutely with a clear and definite landscape behind the superficial landscape, with a truth behind truth, with a reality within reality.
To take an instance from common experience: a stranger, an unknown person, enters our circle. Instinct, working automatically and sensationally, may attract us powerfully towards such a person, with a steady, irresistible attraction. Intuition, on the contrary, uttering its revelation abruptly and with, so to speak, one sudden mysterious cry, may warn us of some dangerous quicksand or perilous jungle in such a stranger's nature of which instinct was totally ignorant because the thing was what might be called a "spiritual quality" lying deeper than those sensational or magnetic levels through which instinct feels its way.
